Caravan Maintenance Tips for Beginners

The Beginner's Guide to Caravan Maintenance (2026 Edition)

Owning a caravan offers unparalleled freedom, but it also brings the responsibility of maintaining a complex vehicle that combines automotive engineering with domestic utilities. Whether you own a lightweight Swift Basecamp Plus or a flagship Bailey Unicorn Cartagena, a proactive maintenance regime is the difference between a stress-free holiday and a costly breakdown. This guide outlines the essential habits for the modern caravanner.

1. Pre-Trip Safety Checklist

Never head off on holiday without performing these five essential checks. If you are unsure about your caravan's weight limits, use our Caravan Towing Calculator to ensure a safe match.

• Tyres and Wheels: Check pressures against the manufacturer's plate (including the spare). Inspect for sidewall cracking. Crucial: Re-torque wheel nuts after the first 25–50 miles of any wheel removal. Most caravans require 110Nm to 130Nm, but always check your handbook.
• Lights and Electrics: Connect your 13-pin plug and verify indicators, brake lights, fog lamps, and number plate illumination.
• Hitch and Brakes: Ensure the hitch head clicks into place securely. Clean stabiliser pads with brake cleaner if they groan. Check the breakaway cable is routed correctly and the handbrake holds on a slope.
• Noseweight: Use a noseweight gauge to ensure you are within the limit of both your caravan hitch and your towcar's towball.
• Gas Safety: Ensure bottles are strapped tight. Check pigtail hoses for signs of perishing or 'orange peel' texture.

2. Monthly In-Season Maintenance

Keep your caravan in peak condition during the summer months with these quick tasks:

• Water System: Run the pump and check for drips under the van. Listen for the pump 'cycling' when taps are off—this often indicates a hidden leak.
• Battery Health: Ensure terminals are clean. If you aren't using the van, top up the leisure battery monthly or use a solar regulator to maintain charge.
• Seal Care: Treat window and door rubber seals with a silicone conditioner to prevent them from sticking and tearing.
• Chassis: Lightly grease corner steady threads. Avoid over-greasing, as this attracts road grit which can grind down the threads.

3. Seasonal & Winter Care

Properly 'winterising' your caravan can save thousands in repair bills. For more on long-term care, see our guide on the Servicing schedule.

• The Big Drain Down: In winter, open all taps (including the shower) to the central position, open the yellow drain-down valve, and remove the shower head. Frozen water in a plastic tap will crack the internal cartridge.
• Damp Prevention: Stand cushions vertically to allow airflow. Use a pinless moisture meter to check corners and around windows. Readings above 15-20% require professional investigation.
• Sterilisation: Every spring, flush the system with a food-safe cleaner (like Puriclean) to remove biofilm from the pipes.

4. Tyres, Brakes, and Running Gear

Caravan tyres rarely wear out through tread depth; they fail due to age and UV degradation. For more information on specific models and their running gear, browse our Caravan Models hub.

• The 5-Year Rule: Replace tyres every 5 years, and never exceed 7 years, regardless of how much tread is left. Check the DOT code on the sidewall for the manufacture date.
• Brake Service: If the caravan 'shunts' against the car when braking, or if the handbrake pulls up very high, your brake shoes need professional adjustment.
• Shock Absorbers: Check for oil leaks on the dampers. Modern models like the Swift Challenger or Coachman Laser 665 often feature sophisticated chassis setups that rely on functional shocks for stability.

5. The Annual Habitation Service

While DIY maintenance is great, a professional habitation service is non-negotiable. An Approved Workshop Scheme (AWS) technician will check:

• Gas tightness and carbon monoxide emissions.
• 230V and 12V electrical safety.
• Full damp report using professional-grade equipment.
• Chassis and braking system integrity.
